Google is busy building its own version of social news reader which is code named Propeller. It is speculated to rival several other such apps like Zite, Pulse, Flipboard, Livestand and Editions. It is being made for iPads and Android tablets specifically. Google being the natural search specialist can surely make a killer of an app. Some users who have had an initial peek of the app have given a positive review. It remains unknown when it is going to be released.
